MOPH Lebanese Ministry of Public Health; IC confidence interval
*Cumulative number reported by MOPH until January 15, 2021
**Estimated number of subjects with previous COVID-19 calculated by multiplying the seropositivity rates for each governorate by the estimated population size
***Percentage of underestimated cases = (Estimated total number of seropositive − registered cases up to 15/1/2021)*100/total population
